She said, "[Tyler Mook] is still very much a person of interest. He has never really cooperated with our agents as far as sitting down and giving them an interview about the last time he saw her."

According to aFacebook pagededicated to finding Shelley, Mook's mother now has custody of her little girl, and she is living in Pennsylvania.

"She doesn't really have a champion here who is speaking for her on a weekly, monthly or daily basis, so I think the agent on this case feels like he needs to do that for Shelley," said Helm.

A family spokesperson told Nashville's News 2, "Everyday we hold out hope that the person responsible will be held accountable."

Sunday, September 9, 2012

The Thursday search for Shelley Mook was unfruitful, leading to the official search being called off, once again. This missing Tennessee teacher may never be found at this rate, and with her ex-husband being uncooperative with the search, detectives are only facing an uphill fight.

The search was ended Friday for Shelley by the Tennessee Bureau of Investigation. After searching a large area around Cowan, there was little else they could do. This case, sadly, appears to be going cold as ice. It's been well over a year, and her ex-husband is still refusing to take a polygraph test and won't cooperate with the search for her. It's been speculated that he may have harmed her, considering her carwas discovered not long after she was reported missing, and it was burned to a crisp.

Hopefully this isn't the end of Shelley Mook's case, but when it comes to missing women in Tennessee, these things can last for years and years.

"Unfortunately, they came up empty-handed," Tennessee Bureau of Investigation spokesperson Kristin Helm said this morning.

"They didn't find anything," Bedford County Sheriff Randall Boyce said today. Several of his detectives were involved in the search, he said.

New information

"Special agents of the TBI have recently received information that led them to search the CSX train yard in Cowan," Helm said.

She did not disclose specifics, but Boyce said he heard that an employee of the train yard had "smelled something" around the time Mook went missing.

WSMV-TV reported Thursday that Mook's ex-husband, Tyler Mook, had worked for CSX Railroad at the Cowan yard.

Tyler Mook has been considered a "person of interest" in the case since his ex-wife's disappearance, investigators say. Several of his relatives live in Franklin County.

Mook's lawyer has consistently refused comment.

Wide area

The search, led by the Tennessee Bureau of Investigation, lasted from 8:30 a.m. to 1 p.m. and spread out from a command post at the train yard, Helm said Thursday.

Mountainous areas of the county, including Keith Springs Mountain, were also searched, according to investigators.

The Bedford County detectives, Bedford County Fire Department and Bedford County Emergency Management Agency were joined by the CSX Railroad Police, Franklin County Sheriff's Department, Cowan police, Franklin County EMA, Maury County EMA and Search and Rescue and the Tennessee Emergency Management Agency.

Background

Shelley Mook, a reading teacher at Harris Middle School, was last seen on the afternoon of Feb. 28, 2011, at Tyler Mook's home outside Shelbyville as she dropped off their daughter on her way to Murfreesboro, where she was to meet a maintenance man at an apartment complex. Her burned car was found that night near Murfreesboro.

The Tennessee Bureau of Investigation has renewed its search in rural Franklin County for missing Shelbyville teacher Shelley Mook after receiving new leads.

A command post was set up Thursday morning along the CSX railroad tracks in Cowan, Tennessee and officials and volunteers were conducting a ground search of the area.

Mook has been missing since she left Harris Middle School on the afternoon of February 28, 2011.

Investigators believe she went to her ex-husband, Tyler Mook's home to drop off their daughter.

It is believed that Tyler Mook was the last person to see the young mother alive.

Mook was supposed to meet a maintenance man at her new apartment in Murfreesboro after dropping off her daughter, but never made it.

Her car was found burned out in Rutherford County later that night.

TBI spokesperson Kristin Helm told Nashville's News 2 Tyler Mook is still considered a person of interest.She said, "[Tyler Mook] is still very much a person of interest. He has never really cooperated with our agents as far as sitting down and giving them an interview about the last time he saw her."

According to a Facebook page dedicated to finding Shelley, Mook's mother now has custody of her little girl, and she is living in Pennsylvania.

"She doesn't really have a champion here who is speaking for her on a weekly, monthly or daily basis, so I think the agent on this case feels like he needs to do that for Shelley," said Helm.

A family spokesperson told Nashville's News 2, "Everyday we hold out hope that the person responsible will be held accountable."

Anyone with information on Mook's whereabouts should call the Bedford County Sheriff's Department at 931-684-3232, the Rutherford County Sheriff's Department at 615-904-3049 or the Tennessee Bureau of Investigation at 1-800-TBI-FIND.

It's been 18 months since Shelley Mook was last seen, but new developments in the case had search crews back out in Franklin County on Thursday looking for the missing mother and teacher.

Mook, a Shelbyville English teacher, has been missing for about a year and a half, and in that time the Tennessee Bureau of Investigation has named her ex-husband as their prime suspect in her disappearance.

Shortly after her disappearance, Mook's car was found burning in a field in Murfreesboro.

The TBI wouldn't disclose what prompted the new search, but about 10 other law enforcement agencies joined the TBI in searching a CSX rail yard in Cowan, TN.

Family and friends said the fact search crews were out again was a hopeful sign.

"I just hope it opens people's eyes to know this is not ended. It is not going to stop until we find what happened," said friend Brittany Brooks.

At this point, investigators are looking for a body, and family and friends said they are looking for closure and justice.

"I hope that nobody ever thinks that after two years or three years if we don't find anything that it will be over, because it won't until something is found and until somebody is found responsible," Brooks said.

Channel 4 News has confirmed Mook's ex-husband's brother worked for CSX, the company that owns the tracks and area where workers searched, but the TBI isn't elaborating on any possible connection.

A former coworker said Tyler Mook was fired from his job back in December. That coworker said no one she knows has seen or heard from him since then.

Channel 4 contacted Tyler Mook's attorney Thursday to see if they had anything to say about the newest search, but the only comment was "no comment."

NASHVILLE, Tenn.- Officials from the Tennessee Bureau of Investigation led a search missing school teacher Shelly Mook, who has been missing for more than 18 months and presumed dead by police.

On Thursday, TBI officials received some new information about an area near the CSX train yard in Franklin County. They were hoping they'd find some sign of the missing teacher. Fifty people from several law enforcement agencies joined the effort in Cowan, Tennessee.

Mook has been missing since February 28, 2011. She was last seen by her ex-husband when she dropped off their 4-year-old girl at his home in Shelbyville. About 12 hours later on March 1st police found her burning car near Murfreesboro.

A TBI spokeswoman said the agents in charge of the case felt the rail yard in Cowan could be a spot where someone could have dumped her body.

"The agent has developed some information through the course of his investigation and determined this was an area that we feel targets family members who were familiar with and knew their way around," said Kristin Helm, spokesperson for the TBI.

The TBI said their main suspect all along has been Mook's ex-husband. They said he has been uncooperative throughout the investigation. Police said he was the last person who saw her. He reported her missing, but not until the day after the car was found. Although he is the main focus, but the TBI is not ruling out the possibility that someone else was involved.

TBI's Kristin Helm has consistently stated that Tyler Mook "is still very much a person of interest. He has never really cooperated with our agents as far as sitting down and giving them an interview about the last time he saw her". Helm has also previously stated that Mook has not been cooperative: "Anytime you have someone who is not really helping you who may have been the last person to see someone. That makes it difficult as well". Helm also previously stated that Mook "is the primary person of interest in this case".
